Can a screw pump be evacuated? What consequences will arise if time is taken away for a long period? Screw overheating, deformation, pump damage?
:Dizzy: In my opinion, this can lead to heating of the screw, deformation, and damage to the pump
I feel that I can find some time for this; the way our unit operates makes it feasible. After all, there’s no guarantee that there will always be material available for that screw pump.
Prolonged operation can cause the screw to heat up; once oil turns into vapor, the screw will wear out. Over time, this can lead to a decrease in the flow rate of the screw pump, and even a drop in pressure.
Prolonged operation can cause the screws to overheat and wear against each other; a large gap between the screws leads to a reduced flow rate of the screw pump and a decrease in power output. In severe cases, it can cause the screws to interlock with each other, leading to pump damage.
Severe wear of the screw can also lead to damage to the bearings or mechanical seals
A screw pump is a positive-displacement pump; its flow rate remains constant. It can withstand vacuum conditions, but prolonged exposure to vacuum will definitely cause damage to the equipment.
